准集中式限价订单簿中的订单流与市场状态

文章 arXiv papers · 作者: Martin D. Gould et al.

总结

本研究考察准集中式限价订单簿,在这种订单簿中,机构只能与双边信用额度充足的交易对手进行交易。研究分析采用这种结构的大型电子交易平台的高质量数据,重点关注该环境中的订单流和市场状态。

报告结果与其他限价订单簿研究中常见的发现存在许多显著差异。研究还发现,订单流和市场状态的分布会因交易日而异,但通过简单的线性缩放,可以将它们对齐到一条共同曲线上。基于这一模式,研究提出了针对单个交易日的半参数模型。该模型的表现与参数化曲线拟合方法相近,同时所需计算更少,实施速度也更快。证据仅适用于所研究的平台和数据,因此摘录无法证明所观察到的缩放规律或模型表现适用于其他交易场所或市场。

核心观点

  • 准集中式订单簿将交易限制在双边信用额度充足的交易对手之间。
  • 实证分析报告的结果与其他限价订单簿研究中描述的规律存在显著差异。
  • 通过线性缩放,可将每日订单流和市场状态分布对齐到一条共同曲线上。
  • 半参数单日模型的表现与曲线拟合方法相近,实现更简单、速度更快。

A quasi-centralized limit order book (QCLOB) is a limit order book (LOB) in which financial institutions can only access the trading opportunities offered by counterparties with whom they possess sufficient bilateral credit. We perform an empirical analysis of a recent, high-quality data set from a large electronic trading platform that utilizes QCLOBs to facilitate trade. We find many significant differences between our results and those widely reported for other LOBs. We also uncover a remarkable empirical universality: although the distributions describing order flow and market state vary considerably across days, a simple, linear rescaling causes them to collapse onto a single curve. Motivated by this finding, we propose a semi-parametric model of order flow and market state in a QCLOB on a single trading day. Our model provides similar performance to that of parametric curve-fitting techniques, while being simpler to compute and faster to implement.
